Phyllodes tumor in B-mode ultrasound is appreciated as a solid, omogeneous lesion [6,7] Fig. The incidence of metastases is strictly correlated to the degree of histologic aggressiveness.

Associated Data Supplementary Materials mmc1. Il color Doppler ha un ruolo nella valutazione delle lesioni mammarie?

Giant juvenile fibroadenoma of the breast: a clinical case.

Open in a separate window. When a lesion has the typical features of a fibroadenoma on ultrasound and there are no clinical red flags they can be safely followed clinically. Color Doppler signals from breast tumors. They are assumed to be aberrations of normal breast development ANDI or the product of hyperplastic processes, rather than true neoplasms.

Number of vessels, blood-flow velocity, and intra-tumoral vessel resistance did not permit clear differentiation between malignant and benign tumors [4]. In some cases the whole lesion is calcified.

US scan reveals a hypoechoic mass Fig. Check for errors and try again. Log in Sign up. B-mode, color and power Doppler ultrasonography of the male breast. The vessel architecture of malignant tumors is known from pathologic studies: Typically seen as a well-circumscribed, round to ovoid, or macrolobulated mass with generally uniform hypoechogenicity. Calcification may also present as crushed stone-like microcalcification which makes differentiation from malignancy difficult.

Case fibroadeboma Case 1. Fibroadenomas that fibrozdenoma high stromal cellularity or containing adenosis complex fibroadenomas often show internal vascularization at Color Doppler, differently from the fibrosclerotic or hyalinized ones that may show small peripheral vessels but not internal flow.

Published online Mar Lymphomas may develop multiple feeding vessels that however usually enter through the hilum of the lymph-nodes. Malignant tumors have a tendency to show increased vascularization, but avascular tumors may be found as well as hypervascular benign tumors.

In other instances US may find a complex mass with solid and cystic fibrozdenoma Fig. A schematic review of color Doppler diagnostic criteria, indicating a benign or malignant lesion, are described. Fibroadenomas have a spectrum of features from the well-circumscribed discrete oval mass hypo- or isodense to the breast glandular tissue, to a mass with macrolobulation or partially obscured margin.

Color Doppler ultrasonography permits to assess the features and evolution Fig.

They usually occur in women between the ages of 10 and 40 years. J Magn Reson Imaging. Sometimes a thin echogenic rim pseudocapsule may be seen sonographically. Ultrasonography using Color Doppler can depict vascularization in thick-walled cysts, allowing the distinction between old fibrotic cysts with low level internal echoes and abscesses or infected galactoceles, where wall hyperemia is associated with fluid-debris pus levels.

When found in an adolescent girl, the term juvenile fibroadenoma is more appropriate. Color Doppler ultrasound may be valuable also in assessing the efficacy of neoadjuvant chemotherapy and in particular of antiangiogenesis treatments. Ultrasonography of the male breast. Click here to view. Hence, they rarely present after the age of 40 years.

Please review our privacy policy. Fibroadenomas have usually a harmonic vascularization with 3 vessel types: In the first studies fibroadwnoma was ecografiq as signals were more numerous and stronger in breast tumors [1,2]. Ecogradia Doppler flow image shows high vascularity in the mass B, C.

US image shows a hypoechoic lesion, with irregularly shaped A ; color Doppler shows vessels with irregular course, sinusoids, and arteriovenous shunts B, C. However, intra-tumoral blood-flow analysis by color Doppler ultrasonography correlates well with histological grade and aggressiveness of the cancers, and can eckgrafia used as first step assessment of the efficacy of neoadjuvant and antiangiogenesis treatments.
